A Brief Review on Normal Pressure Hydrocephalus Diagnosis in Primary Neuropsychiatric Care Settings

Abstract

Normal pressure hydrocephalus (NPH) is clinically characterized by the triad of mental deterioration, gait disturbance, and urinary incontinence. Correct diagnosis and referral of patients is important because NPH is a potentially treatable cause of cognitive decline and should be distinguished from more common forms of irreversible dementia. Unfortunately, it remains to be a rather underdiagnosed and controversial neuropsychiatric entity even in countries with modern healthcare systems. The diagnostic process is complicated by diverse clinical presentations, especially when the classical triad is incomplete or atypical such as with psychiatric symptoms. This manuscript aims to briefly review atypical clinical presentations of NPH and basic radiologic findings associated with it, and outline some recommendations to primary care physicians for diagnosis and referral.
